Can Dm8148 boot logo Support 720p60 on DVO2?

Hi everyone,

Hi everyone,

   I found in the  app note that saying DVO2 cannot support resolution above 480P. But I need the resolution 720P60,  what is the reason for this limited ??  thank you

here is the describe by the doc in DVR_RDK:

<install directory>\DVR-RDK\DVR-RDK\DVRRDK_03.00.00.00_Docs\AppNotes\DM81xx_DVR_RDK_Boot_Logo_on_External_Device.pdf

814X/810X

 Any bitmap of less than 720x480 resolution can be used as a boot time splash screen, with the uboot command

Note: HDMI TV should support 480P60 mode

    Hi zhuohua,

    If you are able to display video contents while running dvr-rdk with 720p display, you will be able to display this resolution on boot logo also. 

    I think you were already able to display color bar test pattern on boot logo for this resolution on DVO2. So it is now just enabling grpx on this venc. You just need to configured grpx for 720p resolution, provide correct graphics image and connected it to the blender. you could find code for this tasks in the confguregrpx List api in boot logo code.

    Regards,
